This invention relates to an improved and novel identification tape plow, designed to be utilized to lay identification tapes of plastic, polyethylene or other indestructible material beneath the surface of the earth to identify cable lines, pipe lines or other underground installations laid thereunder to designate the subterranean installations and eliminate the necessity for complete excavation to identify said installations.

The improved identification tape plow structure may readily be aflixed to existing cable or pipe laying equipment and may be utilized in conjunction with the laying operation thereof, if desired.

In the past, after cable, tubing or pipe installations have been made it has been diflicult, and at times impossible, to identify the subterranean installation without excavating to the full depth thereof and this has necessitated a difficult and expensive excavation operation to so identify the subterranean installation.

Further, when the identification tape equipment of the present invention is utilized, persons excavating in the area will be readily advised that they are operating over such cable or pipe systems when they cut the line of the tape in their excavating operation.

The invention broadly contemplates the provision at the rear extremity of a cable or pipe laying machine of improved blade means of comparatively narrow width, above which are provided readily rotatable rolls of identifying tape designed to be passed downwardly through rectangular tube means provided at the rear or trailing extremity of the blade and thence passed outwardly through the rear extremity of the shoe of the blade over opening means designed to extend the tape to its full width as it is laid in the foot of the cut made by the blade. As the tape issues from the rotatable roll above the blade tube it is passed downwardly over appropriate finger or roller means which fold it longitudinally upon itself, greatly reducing its width and permitting the folded tape to be pulled downwardly through the attenuated, rectangular tube means provided along the rear edge of the blade in folded condition, thus permitting the use of tape means of comparatively small width as compared with the ultimate width of the tape as it is laid in the ditch cut by the blade.

As the tape must be folded longitudinally upon itself for passage down the tape tube along the trailing edge of the blade it is necessary to provide spreading or extending means at the lower extremity of the tape tube to open and spread the folded tape as it issues therefrom into the foot of the cut made by the blade and its bottom shoe.

Two preferred embodiments of the structure are shown in the drawings and are described in detail in the specification.

' folding means for the tape as it issues from the rotatable roll mounted above the blade -to fold the tape longitudinally along its median line to enable its downward passage through a narrow tube aflixed to the rear edge of the blade.

It is another object of this invention to provide improved means at the lower end of the tape tube for unfolding or flattening the tape upon its issuance from the lower end of the tube to permit its being laid flat at its full width in the foot of the cut made by the blade shoe.

It is another object of this invention to provide such tape laying structure which may readily be applied to existing excavating equipment and which further may be used in conjunction with existing cable or pipe laying blades.

Other and further objects of this invention will become apparent as this specification proceeds.

FIG. 7 is a side view, partially broken away and in phantom, of another embodiment of the improved tape laying structure, and

FIG. 8 is a rear view of the embodiment shown in FIG. 7, partially broken away and in phantom.

In the drawings, like reference numerals identifying like elements throughout, 10 designates the blade structure per se which is preferably of conventional structure and narrow width, of the type not requiring a back fill and making a self-closing cut in the ground, and is provided at its lower extremity with forwardly reduced triangular cross-section shoe means 11, provided with a triangular, pointed forward extremity 12 and progressively enlarged to rear surface 13 of frusto triangular shape.

Blade shoe 11 is provided along its downwardly in clined, forward upper surface with a flattened holding plate 14, as shown, of greater width than the forward extremity of shoe 11 and extending outwardly therefrom an appreciable distance therefrom at its forward extremity 15. At its rear extremity shoe 11 is provided with recess 0, extending its full width, as shown in FIG. 6, for the reception of the tape unfolding head, as will hereinafter be discussed in more detail.

As shown, blade 10 is preferably sharpened along its forward or leading edge 16 and is provided at its upper extremity with a forwardly extending bracket means 17 provided with bolt holes 18 whereby it may be bolted or otherwise affixed to the frame of the supporting vehicle.

At its upper extremity, blade 10 is provided with rod means 19 which is angularly bent or inclined at its forward extremity 20 for afiixation to the plate means 17 of the blade 10. Rod 19, as shown, is preferably aflixed to the upper extremity of blade 10 as by brazing, welding or bolting and is angularly inclined upwardly and rearwardly at its rear extremity and thence bent at right angles to provide axle means 21 for a roll of identifying tape 22 which is slid thereover for rotation thereon.

It will be noted that the axis of tape roll 22 on its mounting axle 21 lies at right angles to the plane of blade 10 whereby the tape 23 when laid in the ground at the foot of the blade will lie to its full width at right angles to the blade 10 in the cut made by shoe 11.

Aflixed to the rear extremity or trailing edge of the blade 10, as by brazing, welding or othermeans is a tape tube 24, which is preferably of high abrasive metal and elongate, rectangular shape comprising side walls 25 and 26 and rear wall 27, preferably formed in a unitary, rectangular box-shape and of a width equal to the Width of blade 10 so as not to impede the passage of blade 10 through the ground. As shown, tape tube 24 is preferably of substantially the same height as blade 10 and extends from substantially the top of the trailing edge thereof to a point above its lower extremity at the top of foot 11 of blade 10. In rearward depth, tape tube 24 is preferably slightly deeper than one-half the width of the tape being laid. Thus, for a 6" tape the tube 24 should be about 3 /2" in rearward depth, to allow free movement of the longitudinally folded tape therein.

At its upper rear extremity, tape tube 24 is provided with forwardly inclined finger member 28 which, as shown, comprises a flattened and bored lower extremity 29 provided with bore 30 from whence finger 28 is angularly inclined forwardly in angular section 31 of appreciable length and is then rebent at its upper extremity into rearwardly inclined section 32 which is angularly disposed with respect to section 31 at approximately 90. Finger 28 is preferably of polished metal and of rounded or circular cross-section throughout sections 31 and 32 thereof. Curved bight 33 is provided at its forward, upper extremity between sections 31 and 32 for a purpose hereinafter to be discussed at more length.

It will be noted from FIG. 2 that the curved bight 33 of finger 28 is positioned substantially above the forward or leading edge of tape tube 24 and acts as a guide and folding means for the tape issuing from roll 22 as it enters the upper, open extremity of tube 24. Finger 28, as shown, is preferably affixed by means of bore 30 in its flattened, lower extremity to the upper rear Wall 27 of tape tube 24 by means of bolt 34 and wing nut 35, bolt 34 being welded or otherwise affixed to the upper rear face 27 of tube 24.

At its enlarged rear extremity, triangular blade shoe 11 is preferably provided with an enlarged open recess 0, as shown in FIG. 6, to provide a housing for tape unfolding and flattening head 36, which is shown in FIGS. 2, and 6. As shown, unfolding head 36 is preferably smoothly curved downwardly at its forward ridged extremity and is laterally cut back to each side of center boss 37 thereof, widened at its lower extremity 38, being reduced at its upper, forward center boss at 39 to substantially the width of the folded tape as it issues from the lower extremity of tape tube 24 and then being progressively widened from its median forward boss section 40 to its full width, or the full tape width, at its bottom forward extremity at 41. The rear surface of head 36 is preferably flattened, as shown, and is bored at 42 to receive a bolt 43 passed through the vertically slotted rear face of shoe 11, which maintains head 36 in proper vertical position within the recess 0 in the rearward portion of blade shoe 11. The rear center surface of blade shoe 11 is preferably vertically slotted at 44 for ready insertion thereinto of head 36 and bolt 43.

It will thus be seen that as tape 23 is pulled off roll 22 the bight 33 of finger 28 impinges against the center of the flat tape, folding it along its median line to a narrow width to allow passage of the longitudinally folded tape downwardly through tape tube 24. When the folded tape reaches the curved boss 37 at the forward extremity of unfolding head-36 beneath tube 24 boss sections 39 and 40 of head 36 register in the fold of the tape and, as the tape pulls downwardly thereover, the progressively widening boss sections 40 and 41 of the forward surface of 4 head 36 unfold the tape and flatten it out, as shown, to its full width, to be laid flat in the cut made by the bottom of angular shoe 11.

It will be noted that the forward bight 33 of folding finger 28 and the forward boss sections 39 and 40 of shoe 36 are vertically aligned, respectively, beneath finger 28 and the forward, inner edge of tape tube 24 in the same vertical plane and thereby maintain the folded tape in proper longitudinal alignment within tape tube 24 while in folded condition therewithin. Thus, as tape is pulled off roll 22 and passes downwardly therefrom, its median portion first impinges against bight 33 of finger 28 and the tape is thus equally and longitudinally folded thereabout for passage downwardly through the tape tube 24. As the folded tape reaches bosses 39 and 40 of head 36, the most forward line of head 36, it fold impinges against the forward boss 40 and it is pulled downwardly over the progressively widening section 41 of the lower, forward section 41 of head 36, progressively unfolding the tape until as it passes beneath the wide bottom edge of head 36 into the foot of the cut made by blade 10 and its shoe 11 the tape is in its original flat condition and is laid flat along the foot of the cut made by the shoe 11.

In this embodiment, the lower extremity of the tape tube 24 may be downwardly triangularly enlarged to an open bottom orifice to house unfolding head 36, the enlarged lower extension of tube 24 conforming in crosssection to the rear face of shoe 11.

Another embodiment of this invention is shown in FIGS. 7 and 8. In this embodiment, a similar tape tube 24 is appropriately aflixed down the trailing edge of the blade 10 and is again of the same or substantially the same width as blade 10 and then is downwardly enlarged at its lower extremity in triangular form to conform to the rear surface of blade shoe 11. In this embodiment of the invention, a pulley is substituted for the folding finger 28 of the first embodiment and a lower pulley, curved spreader bar and bottom roller are substituted for the head 36 thereof, as will hereinafter be more fully described.

Thus, referring specifically to FIGS. 7 and 8 of the drawings, the tape roll is again rotatably mounted on rectangular arm 21 of rearwardly extending rod 19, the lower portion 20 of which is appropriately affixed to the upper extremity of the bracket 17 of blade 10.

As in the first embodiment, arm 19 is rearwardly inclined so as to center tape roll arm 21 over the leading edge of the tape tube 24, which, as in the first embodiment, is vertically aflixed to the trailing edge of blade 10 in vertical alignment therewith.

Aflixed above the mouth or open upper extremity of tape tube 24 is pulley 45 which is preferably formed of aluminum or other light, strong metal and is rotatably mounted on axle 46 in ball-bearing races 47, directly above tape tube 24 and in vertical alignment therewith. As shown, pulley 45 is preferably of substantial diameter and of slightly less width than the width of tape tube 24 and is supported thereabove in parallel arms 48 and 49, axle 46 thereof being supported between the upper extremities of arms 48 and 49 aligning the median plane of pulley 45 with the vertical axis of tape tube 24. Arms 48 and 49 are preferably brazed, welded or otherwise alfixed to the rear, upper surface of tape tube 24, as shown.

Rotatably mounted beneath the lower extremity of tape tube 24 is lower pulley 50 rotatably mounted on axle 51 between parallel arms 52 and 53 extending upwardly within the enlarged lower portion of tape tube 24. At their rear extremities, arms 52 and 53 are preferably brazed or welded to base plate 54 of the base assembly.

It will be noted that the forward or leading edges of pulleys 45 and 50 lie in a vertical plane spaced rearwardly of the forward, vertical edge of tape tube 24 to allow clearance therebetween for the tape as it passes downwardly through tube 24.

In this embodiment of the invention, tape tube 24 is preferably enlarged outwardly at its lower lateral edges into a triangular housing T defined by lateral walls 55 and 56 and rear wall 57, conforming in shape to the triangular rear surface of shoe 11 and spaced rearwardly therefrom.

Beneath lower pulley 50- and positioned centrally of the vertical axis thereof is a rearwardly curved spreader bar '58 which, as shown, extends substantially the full width of the lower, triangular housing T of tape tube 24. Spreader bar 58 is preferably formed of polished metal and is smoothly curved rearwardly in curved arms 59 and 60, the ends of which, as shown, are afi'ixed to base plate 54, as by welding. It will be seen that curved spreader bar 58 is inclined downwardly beneath pulley 50 and its forward apex 61 lies beneath the forward edge of pulley 50 in the same vertical plane. Thus, as tape is pulled downwardly over pulley 50 the apex 61 of spreader bar 58 meets the spreading tape and its rearwardly curved arms 59 and 60 act to spread the tape flat.

As shown in FIG. 7, the forward apex 61 of spreader bar 58 impinges against the median line of the tape directly below and rearwardly of the forward edge of pulley 50 and in the plane thereof to implement the unfolding of the tape, which is then progressively completed by rearwardly curved outer arms 59 and 60 of bar 58.

Mounted laterally across the lower, open extremity of the enlarged lower housing T of tape tube 24 and extending substantially the full width thereof is tape roller 62 mounted on axle 63 between parallel brackets 64 and 65. Brackets 64 and 65 are also atfixed to base plate 54 at their rear edges, as shown. It will be noted that the lower edge of pulley 62 extends downwardly a slight distance beneath the lateral walls 66 and 67 of the triangular lower housing T of the tape tube. Roller 62, as shown, extends below the lower extremity of the housing in a plane parallel to that of curved .spreader bar 58 and at right angles to the vertical plane passing through the axis of pulleys 45 and 50.

It will thus be seen that base plate 54 supports the entire assembly for opening the tape as it issues from tape tube 24. Thus, arms 52 and 53 supporting axle 51 of pulley 50 are affixed to base plate 54. Similarly, the rear extremities of curved arms 59 and 60 of spreader bar 58 are afiixed thereto as are the brackets 64 and 65 supporting axle 63 of roller 62. 1

Base plate 54 is itself vertically adjustably supported in close bearing relation with rear wall 57 of the lower, triangular extension T of tube 24 by means of lock nut 68 and doll pin 69 which are vertically aligned and fitted in vertical slot 70 in the rear, center surface of rear plate 57 thereof. Thus, vertical adjustment of base plate 54 will adjust the vertical position of the entire unfolding assembly in housing T.

It will thus be seen that in this embodiment of the invention upper pulley 45 takes the place of finger 28 of the first embodiment and impinges against the median line of tape 23 as it is pulled downwardly from tape roll 22 and acts to fold tape 23 longitudinally in equal sections. for passage downwardly through tape tube 24. Further, lower pulley 50, aligned in the same vertical plane as upper pulley 45, holds the tape in partially unfolded condition and thus directs the opening tape downwardly into impingement with the curved forward extremity 61 of curved spreader bar 58, which acts progressively to spread the tape 23 outwardly within lower triangular housing T into flattened condition to the full width of lower roller 62. Roller 62 forces the tape in fully flattened or unfolded condition into the bottom of the cut made by the lower surface of shoe 11 and thus lays it in flattened condition along the foot of the trench as the tape-laying vehicle is pulled in a forward direction.

Obviously, the tape being laid must be of slightly less width than the width of the blade shoe 11 at its widest, rear extremity. In this embodiment of the invention, friction against the tape is decreased by pulleys 45 and 50 and roller 62 and ease of laying thereof in the foot of the trench cut by the blade 10 and shoe 11 is thus facilitated.

In operation, in both embodiments of the invention, the tape is initially pulled downwardly from the tape roll over the upper finger or pulley means whereby it is folded and is then pulled downwardly through the tape tube 24 over the unfolding structure at the bottom thereof and outwardly through the open, rear orifice and pulled out to a considerable length for initial laying in the foot of the cut made by the blade and shoe. Once the tape is started in the foot of the cut, forward movement of the carrying vehicle will continue progressively to pull the tape from tape roll 22, down through tape tube 24 for laying the foot of the cut.

Referring to the first embodiment shown in FIGS. 1-6, the tape tube may be triangularly enlarged at its lower extremity to house unfolding head 36, in place of mounting the unfolding head in the shoe orifice.

The tape laying structure disclosed herein may, if desired, be used in conjunction with the cable or pipe laying operation, with the tape layer blades positioned rearwardly of the cable or pipe line blades whereby the installations and the tapes may be laid simultaneously in one continuous operation. Suitable back fill implements may be positioned therebetween to cover the cable or pipe prior to the laying of the tape thereabove.

The invention is susceptible of numerous embodiments without departing from the spirit thereof. Throughout, equivalents may be substituted for the various elements with-out departing from the spirit of the invention.

The device is capable of laying tapes of any desired width of from 3" to 8" in width or even wider if it is desired to lay tapes of such width.

As aforesaid, the tapes are preferably formed of plastic, polyethylene or other non-deteriorating material and may be provided with any appropriate legend, depending upon the installation they are utilized to identify.

The tape r-olls utilized may be of any desired diameter and may carry any required length of tape, depending upon the length of the installation to be identified. Means may be provided on the tape roll axle to slow rotation of the tape roll and prevent overrun.
